A real life example- Linux Kernel A feature B was tested and released,

Linux Kernel A+1 feature B+1 was tested and released

Now feature B+1 is ported back into Linux Kernel A

How should I call the testing of the this third stage ? Regression is the closest thing, but technically it refers to combinations that were tested before and are being retested now.

  • I think "backward porting testing", or the more succinct "backport testing", gets the point across.

I wouldn't call it backward porting testing at all. Within A, the feature from B is brand new, making it A+2. It's a new feature in its own right. The fact that A, B, A+1 and B+1 were tested and found stable doesn't guarantee that A+(B+1) will be bug free. There isn't another name for that other than "testing".

Perhaps "Backwards Compatibility Testing"?

  • Again- close, but not exact. The ported feature will be an integral part of the older Kernel

  • Got it. Perhaps just "Older Kernel Enhancement Testing" then. Sep 10, 2012 at 13:48
